Thanks to jeweler Adam Campbell, who custom designed the engagement ring for

the son of Caitlyn Jenner, according to People, we can catch a close-up of the huge diamond (see the photo below). On Monday, the Los Angeles-based jeweler posted an up-close-and-personal photo of the four-prong solitaire oval diamond to his Instagram. "HUGE congratulations to my dear friends @brodyjenner and @kaitlynn_carter on their Engagement this week in Bali!" Campbell captioned the photo, which was a split of the engagement ring close-up with a cute couple shot of Jenner and Carter. "I couldn't be happier for you both and was honored to play a small part in your Story. Here's to many years of wedded bliss. Love you both! #engaged."

The couple's jeweler wasn't the only one posting cute pics to Instagram in celebration of the couple's exciting news. The groom-to-be's mom, Linda Thompson, took to the social media site to welcome her future daughter-in-law into the family. "If we look happy it's because we are! CONGRATULATIONS to @brodyjenner & @kaitlynn_carter who got ENGAGED in Nihiwatu! #Family #Love," she wrote on Instagram.

The Hills alum and Carter broke the news of their engagement via Instagram early Friday morning with a semi-steamy photograph. The sweet snap shows the celebrity DJ and his new fianc basking in the sun on vacation with a bikini-clad Carter leaning across her beach towel to kiss Jenner on the cheek. "On May 4th 2016 I got engaged to my lover and best-friend," Jenner captioned the adorable, jealousy-inducing pic, including all the happy marriage emojis possible. "I couldn't be more in love with this woman and I can't wait to spend the rest of my life with her."

Jenner, 32, first began dating Carter, 28, in 2014, accordingly to Us Weekly. If you'll remember, their relationship was considered "too new" for Kim Kardashian to offer her stepbrother a plus one to her Italian wedding to Kanye West, resulting in him boycotting the family affair entirely. Jenner, who was previously romantically linked to The Hills leading ladies Lauren Conrad and Kristin Cavallari, has made the distance between him and his step-sisters very clear.

"I don't see them very often," Brody told Yahoo Style of the Kardashian sisters. "I live out in Malibu, they live in Calabasas. To be honest, I don't even really know Kanye that well at all. I've really only met him one time," Brody said. "That's the one thing that people don't really understand is that we live two completely separate lives. And everybody ties us in together as the Kardashians and the Jenners. I mean, [Kris and Caitlyn] got a divorce, so they're not even technically my family anymore."

Regardless of who gets an invite to this newly engaged couple's wedding or not, one thing's for certain — we're sure that enormous engagement ring on Carter's left hand would definitely be Kardashian approved!
